Abstract
A metal-free, atom-economy and simple work-up domino amination-Knoevenagel condensation approach to construct new coumarin analogous (4a-f and 8a-e) was described. Further, new formyl (5a,d-f) and nitro (9a,d-f) coumarin derivatives were synthesized via C-N coupling reaction of various cyclic secondary amines and 4-chloro-3-(formyl-/nitro)coumarins (1a,c), respectively. The confirmed compounds were screened for their in vitro anti-proliferative activity against KB-3-1, A549 and PC3 human cancer cell lines using resazurin cellular-based assay. Among them, coumarin derivatives 4e and 8e displayed the best anti-cervical cancer potency (KB-3-1) with IC50 values of 15.5 ± 3.54 and 21 ± 4.24 μM, respectively. Also, 4e showed the most promising cytotoxicity toward A549 with IC50 value of 12.94 ± 1.51 μM. As well, 9d presented a more significant impact of potency against PC3 with IC50 7.31 ± 0.48 μM. Moreover, 8d manifested selectivity against PC3 (IC50 = 20.16 ± 0.07 μM), while 8e was selective toward KB-3-1 cell line (IC50 = 21 ± 4.24 μM). Matching with docking profile, the enzymatic assay divulged that 8e is a dual potent single-digit nanomolar inhibitor of VEGFR-2 and EGFR with IC50 values of 24.67 nM and 31.6 nM that were almost equipotent to sorafenib (31.08 nM) and erlotinib (26.79 nM), respectively.

Med Chem 2019; 16:229-243. [PMID: 31309895 DOI: 10.2174/1573406415666190715164834] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 04/05/2019] [Accepted: 06/07/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Urease enzyme catalyzes the hydrolysis of urea into ammonia and CO2, excess ammonia causes global warming and crop reduction. Ureases are also responsible for certain human diseases such as stomach cancer, peptic ulceration, pyelonephritis, and kidney stones. New urease inhibitors are developed to get rid of such problems. OBJECTIVE This article describes the synthesis of a series of novel 1-aroyl-3-(2-oxo-2H-chromen-4- yl)thiourea derivatives (5a-j) as Jack bean urease inhibitors. METHODS Freshly prepared aryl isothiocyanates were reacted with 4-aminocoumarin in the same pot in an anhydrous medium of acetone. The structures of the title thioureas (5a-j) were ascertained by their spectroscopic data. The inhibitory effects against jack bean urease were determined. RESULTS It was found that compounds 5i and 5j showed excellent activity with IC50 values 0.0065 and 0.0293, µM respectively. Compound 5i bearing 4-methyl substituted phenyl ring plays a vital role in enzyme inhibitory activity. The kinetic mechanism analyzed by Lineweavere-Burk plots revealed that compound 5i inhibits the enzyme non-competitively. The Michaelis-Menten constant Km and inhibition constants Ki calculated from Lineweavere-Burk plots for compound 5i are 4.155mM and 0.00032µM, respectively. The antioxidant activity results displayed that compound 5j showed excellent radical scavenging activity. The cytotoxic effects determined against brine shrimp assay showed that all of the synthesized compounds are non-toxic to shrimp larvae. Molecular docking studies were performed against target protein (PDBID 4H9M) and it was determined that most of the synthesized compounds exhibited good binding affinity with the target protein. Molecular dynamics simulation (MDS) results revealed that compound 5i forms a stable complex with target protein showing little fluctuation. CONCLUSIONS Based upon our investigations, it is proposed that 5i derivative may serve as a lead structure for devising more potent urease inhibitors.
